The starfish takes in water into the tube feet, (expanding the tube feet) the water is then forced out of the tube feet, (contracting the tube feet) making it able to grab onto the object.
Oysters secrete an adhesive that makes them stick to rocks. It is a type of cement that is currently being studied as a means to formulate better adhesives for human use.

I am going to dodge the question about them actually having "blood" and say yes. They are exothermic, meaning that they require heat from outside of their bodies to help them stay alive.
This is the basal disc. It is useful in helping the hydrozoans stick to and stay on the rocks around them.
A starfish can reproduce by mating with another starfish or asexually. Asexual reproduction is usually done after a starfish experiences dismemberment. The dismembered arm can grow into a whole new starfish.
Starfish are carnivores (they eat meat) Like clams, oysters, and fish Sometimes starfish eat other starfish
starfish dont migrate they stay in interl zone
Some starfish do indeed eat limpet. These starfish tend to be more aggressive feeders and will pry limpets from their rocks.

Starfish don't swim they crawl around very slowly on rocks in the ocean on their "feet". Sometimes the current can unstick them from their rocks and make them momentarily be "waterborn" but this is not swimming.
They have special suckers on their body which cling to the rocks like suction cups.
Beacuase the cushion starfish has 1000's of little suckers underneath, they stick to the rocks and they are so strong that the waves can't pull them off the rocks, but if we come along and rip it off the rocks, that damaged the cushion starfish.
Some baby starfish stay with their mother until they are able to survive on their own. Others are released as eggs into the water and do not stay with their mother.

Baby starfish of some varieties stay underneath their mom until they are big enough to go off on their own. Most starfish lay hundreds of eggs in the water and do not say with the eggs.
Starfish live in saltwater, on rocks or reefs
